Please recommend a novel that allows the protagonist to travel freely through the modern city and become invincible in the future, and a novel with a similar plot but whose name has been forgotten?

The main character has a ring that allows him to travel to the future, and it's also a system. The protagonist took the modern vegetable,"Chives," and sold it in the future. In the future, vegetables were very expensive, and computers were very cheap. And the protagonist's friend was a very famous painter in the future. Please help me out...

Answer 1

I can recommend a novel to you, and that is "I Have Countless Small Worlds." The main character transmigrated and became the System Master and Samsara Master God. Every day, he developed his own imagination to create a system and bound it to the people of various small worlds. Moreover, the items and missions in the mall had to be done by the main character himself. If they encountered any difficulties, the system would reward them to make them invincible.
